The 140 stamp present Tomato flower. Tomato plants are dicots, and grow as a series of branching stems, with a terminal bud at the tip that does the actual growing. Most tomato plants have compound leaves, and are called regular leaf (RL) plants.
Their flowers, appearing on the apical meristem, have the anthers fused along the edges, forming a column surrounding the pistil's style. Flowers in domestic cultivars tend to be self-fertilizing. The flowers are 1–2 centimetres across, yellow, with five pointed lobes on the corolla; they are borne in a cyme of three to 12 together.
